Uranium(VI) sorption onto kaolinite in the presence and absence of humic acid
We studied the U(VI) sorption onto kaolinite in batch experiments in the absence and presence of humic acid (HA) under different experimental conditions: [U]0 = 1×10-6 M or 1×10-5 M, [HA]0=10 or 50 mg/L, I=0.1 M or 0.01 M NaClO4, pH=3–10, CO2 or N2 atmosphere...

The aim of this study is to explain how the kaolinite-based clay minerals adsorb hexavalent uranium (uranyl ion), and to model uranyl adsorption based on inner-sphere surface complexation with the kaolinite edge hydroxyl sites and outer-sphere complexation with the permanent charge sites...
